ABSTRACT:
A dry shaver has a housing with a head frame floatingly supporting an outer shearing foil. An associated inner cutter is driven to move in hair shearing engagement with the outer shearing foil. The head frame is formed with a stopper which is in use adapted to come into contact with a user's skin. The shaver is characterized in that the outer shearing foil is supported to the head frame by means of a floating mechanism which, when the outer shearing foil is depressed at a given portion by contact with the user's skin, allows an upper end of the depressed portion of the outer shearing foil to displace down beyond the stopper such that the stopper comes into contact with the skin for bearing the depressing force.
